Holding his head from the blow, Derrick sat up and rubbed the sore spot, nearly bumping into the iron pillar again. Feeling something smack into his head, Derrick cringed and felt something fall into his lap. He looked down and found it was a black and green cylinder with a button on top. Standing up with a raised eyebrow, he held it and heard a message sound in his head.

‘I am the changer of shape, seeking to understand the many forms of life. Call for the man of many shapes during your hour of need and I will come, a one man army. Activate the cylinder and in a flash, I’ll be ready to clash.’

“It rhymed. Here goes nothing.” Derrick said bluntly and pushed the button on top of the cylinder. There was a bright green flash and two figures appeared, one seemed to be a slightly older human male, locked in a sword fight with a strange insect like humanoid. Derrick looked at the fight and immediately made flames appear on his hand.

“You’re fighting. Why are you fighting?” He asked, increasing the brightness of the flames a little bit.

The man held his hand up, his opponent pausing. “I suggest you put that flame out.” He turned to Derrick, looking him over.

Derrick closed his fist, causing the flame to go out. “There. You didn’t answer my question though.” He said, placing his hand on his hip.

“Sparring, and now that I see we’ve been summoned, I do believe the match is over.” He flicked his sword, causing the sword to collapse in on itself. He stored it in his pocket, looking at the insect. “That sound good?”

“Yeah, that sounds great...” she, from the sound of her strange, echoey voice, said, stabbing her greatsword into the ground, panting a little.

“Sparring. That didn’t look like sparring to me. What are your names?” Derrick asked, scratching his head and ignoring the echoey quality of her voice for now.

“I’m Jason Hughes and this is my daughter Freya.”

“Hi.” Freya waved, still trying to catch her breath.

“Nice to meet you. I’m Derrick.” Derrick introduced himself and looked at the both of them. “I don’t mean any offense but Freya doesn’t look anything like you.”

“I’m a shapeshifter,” Jason said with a shrug, “So, any reason you called me out here?” he leaned on a wall, eyeing Derrick with a raised eyebrow.

“Shapeshifter. That would explain it then. I don’t think there was a reason.” Derrick answered but immediately ducked as another iron pillar was shot through the entrance, embedding itself in the wall behind him. “That may be a reason?”

“The hell was that?” Jason asked, looking at the pillar, then at the entrance.

Standing in front of the entrance was a man with iron-studded gloves and boots. He wore a black and grey cloak and off-white baggy pants. He had black hair with what looked like iron bolts embedded in his arm and face.

“That would be Gajeel. The Iron Dragon Slayer.” Derrick said as he got up from where he ducked and went to stand beside and Jason and Freya.

“Did I get pulled into another anime?” Jason asked with a sigh, facepalming, “I swear, I better not get punched into a planet again.”

“Again? What happened the first time?” Derrick asked in surprise.

“I had to fight Broley.” Jason answered simply.

“Geh hee.” The man at the entrance said with a wide, toothy smile. He said something else under his breath and transformed his arms into long, metal poles which he spun around in a circular motion. Derrick jumped on to the nearby table when he saw Gajeel begin to spin.

“How tough is this guy exactly?” Jason asked, not seeming the least bit impressed.

“He can bring down an entire guild and force them into hiding. A guild has about hundred or so people in them. He is ranked the strongest in his own guild.” Derrick answered. “There are basically four levels within the guild. C, B, A and S. S class is the strongest and Gajeel is an S class wizard.” Derrick explained further, noticing the look on their faces.

“Right, ok.” Jason nodded. “I don’t exactly know what’s your problem, wizard, but I suggest you reconsider it.”

“I don’t want to reconsider it. I’m doing this because my master said so and plus, it’s fun.” Gajeel answered and, muttering something else under his breath, puffed his cheeks out and let loose a silvery-grey roar that was full of miniscule bits of iron. Jason swept his arm out, erecting a wall of ice that easily stopped the attack.

Derrick looked at Jason with raised eyebrows but not bothering with any questions, ran out from behind the ice wall. Filling his fist with fire, he ran up to Gajeel and punched him in the face. It didn’t have any effect though as Gajeel’s skin turned into iron at the moment of impact. He grinned and picking up Derrick, threw him at the ice wall.

“I gotcha.” Freya’s horn glowed, wrapping Derrick up in her blood red magic. “Just let my dad handle it.” She set him back on his feet, now standing next to her.

“Thanks, Freya.” Derrick thanked her and shook his hand, trying to get rid of the pain of nearly breaking his hand.

Gajeel got an angry look when Freya caught him with her magic. Walking towards the group, he stopped in front of the ice wall and tilting his head to the side for a bit, grinned and mumbling something, turned his hand into a spear. He thrusted the spear through the wall, making a hole in it.

“Having fun?” Jason asked, having suddenly appear behind Gajeel, “I don’t even know why you’re smiling. You can break ice, almost every living thing can do that.”

“I’m smiling because I am having fun. I live for this sort of thing.” Gajeel said, taking his arm out of the wall and whirling around to bash Jason with the spear head. Jason just stood there, not even flinching as the spear hit him, though a large portion of his shaggy hair was severed. “What? Iron Dragon’s Club!” Gajeel shouted, transforming his leg into a large, steel club and forcefully kicked Jason in the abdomen. Once more, Jason didn’t even flinch.

“You are going to have to hit a fuck ton harder than that if you actually want to hurt me.” Jason commented, looking down at him.

“Are you kidding me?” Gajeel asked in disbelief, stopping his attack for a second to eat a bit of iron off the floor. After finishing the iron, he wiped his mouth and clapped his hands above his head, fusing them into a giant sword. He then brought it down on top of Jason’s head, intending to cleave him in two. The blade slammed into Jason head with a loud thunk. He winced ever so slightly, a trickle of blood running down his face.

“Alright, that stung.” Jason pushed the blade aside, cracking his neck.

“That only stung him?” Derrick asked in surprise.

“Dad’s descended from gods and giants, and that guy isn’t exactly Grandpa Gilg.” Freya shrugged, leaning on her sword. “In all honesty, the only reason that guy hasn’t been vaporized or turned into ground beef is because Dad likes to make a good first impression.”

Gajeel was equally surprised. “No way. No way you can survive my Iron God Sword.” He said, getting a slightly scared look on his face. He backed up a bit and made the rest of his body turn into iron scales.

“Alright, I’ll go easy on ya, Omnitrix, Rath.” Jason vanished in a green flash, replaced by a very angry looking tiger man. “Rath is gonna tear you a new one!” he roared, snorting in rage.

“I would like to see you try.” Gajeel said, not phased by the transformation. He got into a battle stance and waited. Rath let out a scream of rage, rush forward, throwing a punch at Gajeel’s stomach. Gajeel blocked it with both arms crossed, the force of the punch making him slide back a few feet. When he stopped, he rushed at Rath and went for a punch to the throat.

“Ha! That tickled!” Rath declared, grabbing Gajeel’s wrist, spinning around, and swinging him into a pillar before tossing him away. Gajeel landed halfway across the city, making a crater path into a few houses. Getting up almost immediately after, he jumped up high and made his way to Rath in leaps and bounds. Soon as he was on top of Rath, Gajeel shouted something and turned his legs into a giant drill. His legs then spun around at a rapid speed as he impacted into Rath. Rath brought his hands together, unleashing a shockwave, sending Gajeel flying backwards.

“Did that one tickle?” Gajeel asked as he flipped around, dragging his hand across the ground to stop himself.

“No, it was more like a bee sting!” Rath snarled, rushing forward. He leapt into the air, arms raised, falling towards Gajeel. In response, Gajeel leapt up into the air as well, transforming his arm into a giant sword and swung it towards Rath. “Omnitrix! NRG!” Rath shouted, turning into an armored form. The sword hit him in his armored head, letting out a loud dong but didn’t do any damage.

When the sword hit, Gajeel’s arm shook from the force of the blow. His arm went back to being covered in scales and when it did, he grabbed a hold of the armored head in both hands. “Metal! Thanks for the snack.” Gajeel thanked him and began munching on the armor, only to break several of his teeth.

“Good luck with that idiot,” Jason said, now sporting a Russian accent, “This armor can only be damaged by taydenite, the hardest substance in the universe.”

Gajeel howled in pain, only to replace his teeth with sharp bits of iron. “That’s better.” Gajeel said, his voice having a metallic edge to it now. Releasing the head, he then fell like a rock, making a miniature crater as he landed. “I may not be able to damage it, but I can sure as hell try.” Gajeel said with a smirk. Puffing out his cheeks again, he then blew iron wind towards the tinhead. It merely plinked off.

“You can’t pierce it moron.”

Gajeel’s response to this was to scream loudly and rush at Jason, giving him quick alternating kicks and punches.

“He transformed. Twice. How?” Derrick asked Freya, his mouth hanging open slightly.

“What do you mean how?” Freya asked, looking at him, raising her eyebrow.

“He went from being a human, to a wrestling cat and then to a Russian bucket. You can’t just switch forms like that!” Derrick answered, walking a bit away from her.

“Well he can, that's why he has the Omnitrix.” Freya followed him, hefting her sword over her shoulder. “And dad isn’t human, he’s Jotun.”

“Jotun. Like an Ice Giant thing from those Norse legends? That would explain the ice wall. And the Omnitrix explains the shifting forms. Now I get it.” Derrick went and sat on the nearby table, looking out at the fight.

“You done yet?” Jason asked Gajeel, crossing his arms, “You’re not getting anywhere.”

Gajeel quit the punching and kicks at the question, feeling slightly out of breath. “I’m not, but why don’t you try hitting me for a change?”

“You really don’t want me to do that.”

“And why not?” Gajeel asked, crossing his arms.

“Because I can vaporize you.” Jason answered simply. Gajeel’s face dropped at that.

“I’ve got iron scales made from my own body. It increases my strength and can increase my durability as well. I’m sure I can survive any blast you throw at me.” Gajeel said seriously.’

Jason tapped the device on his chest, returning to his normal form. “Kaio Ken x200!” he shouted, becoming engulfed in a furious red aura. He assumed a stance, pulling his hands back. “Ka...me...”

“Hey uh...where are we exactly?” Freya asked, taking a step back.

“We’re in the Crystal Empire. A shield is around the city, trying to keep Sombra out. I think, no, I know the shield will collapse when he unleashes that.” Derrick said with wide eyes, immediately scooting back on the table.

“Seriously man, just give up.” Freya cast a few quick spells on herself and Derrick, still backing away.

“Gajeel, she’s right!” Derrick shouted at him, falling off the table and hiding behind it.

Gajeel merely growled at the both of them but after seeing the terrified look in their faces, he realised that maybe he shouldn’t antagonise the guy any longer.

“Ha...Me...” Jason pulled his hands back further, a large sphere of energy forming in his hands.

Taking a breath, Gajeel steeled himself and braced for impact. “I can definitely take this blast.” He growled to himself.

“Ha!” Jason vanished from view. A moment later, a loud explosion filled the air, and a massive blast of energy shot up into the sky. When Gajeel heard the blast, he opened his eyes and looked around. Seeing no-one was there, he then laughed.

“Hahaha! That’s right! Run like a coward!” Gajeel said triumphantly.

“Boo.” Jason had appeared behind him, still rocking the aura. Gajeel jumped a mile high at this, almost scared out of his wits. When he landed, he looked at Jason with wide eyes.

“Don’t do that!” Gajeel growled.

“Are we done here?” Jason asked, crossing his arms, raising his eyebrow.

“With what you just did, yeah, we’re done.” Gajeel said in a sigh, disappointed at not being able to defeat him. His skin turned back to normal and he sat in slump. “I know when I’m beat.”

“That was something.” Derrick commented.

“What were you even trying to do anyway?” Jason asked, dropping the aura, though he was panting rather heavily now.

“Master told me to help out someone here. She must have run off after I knocked a pillar into him.” Gajeel answered, pointing to Derrick. “Considering what he did to that anvil in the back of the shop there, he seemed like a good opponent to fight anyway.” He tried to explain, and moved his finger from Derrick to the partially melted anvil.

“And who is your master?” Freya asked, placing her hand on her hip.

“Master Makarov. He is the master of the Fairy Tail guild.” Gajeel answered with a shrug, stretching his arms into the air to get the kinks out of them.

“Are we cool now?” Jason asked Derrick, raising his eyebrow, “Because I’d rather go help them with Sombra than deal with this idiot.”

“We’re cool. I was meant to get the crystal heart back to Twilight when I was attacked by him.” Derrick answered, moving over to the crystalline statue. “I can’t exactly carry it by myself though.” He said with a sheepish grin, showing the crystal covering his arm.

“How did that happen?” Freya asked, reaching out, rapping his knuckles against said crystal.

“When the shield came down, a bit of something from a smoke monster got cut off and landed on the ground. I went to see what it was and when I picked it up, this started happening. No idea how to stop it, or even slow it down. Princess Cadence and Shining Armor are helping me in figuring out how to though.” Derrick explained, not feeling anything when she rapped against his arm. “It’s spread to just above my stomach and just below my elbow on my other arm.” He added, showing where the crystal was.

“Esuna.” Jason held his hand out, casting a spell on Derrick. Derrick only raised an eyebrow as he felt nothing happen. Looking down at his body, the only thing that seemed to happen to the crystal was make it shrink slightly.

“Didn’t work. What was that meant to do?” Derrick asked in confusion.

“It’s supposed to remove harmful effects.” Jason grumbled, looking at it. “I really hate Sombra’s crystal magic...”

“I don’t even know why it reacted the way it did. Maybe it’s because I’m a Dragon Slayer now? Whatever the case may be, we still need to take this to Twilight and her friends.” Derrick wondered and gestured to the crystal on the melted anvil.

Jason rolled his eyes, scooping up the heart. “Where are they?” he asked, gesturing for everyone to get close to him.

“Her friends are all over the place so the safest bet would be at the castle.” Derrick said as he moved closer, thinking back to when Twilight had directed everyone to go to different places.

“I need the location of a specific person.” Jason insisted.

“Oh. Well why didn’t you say so? Twilight is down on the first floor of the library with Pinkie.” Derrick said with confidence.

“Thank you.” Jason rolled his eyes. He placed a hand on Derrick and Freya’s shoulders before teleporting them to the library, appearing next to Twilight.

“Ah!” Twilight gasped at their sudden appearance.

“I think I’m going to be sick.” Derrick muttered, turning slightly green.

“Oh suck it up ya wuss.” Freya shook her head, looking at Twilight. “Hi Aunt Twi.”

“Yeah, yeah. In a minute.” Derrick said softly, waving his hand and moving a bit away from them.
